Jailbreaking Allows Camera Zoom?

I was at Wrigley field on Monday night for a Cub's game. I saw iPhones everywhere. The guy in front of me had an AT&T jailbroken phone (I saw the AT&T in the corner). I also noticed the different icons on the home screen.

I watched him take a pic. When he started the camera there was a slider on the right side of the screen that he used to zoom in (a lot) to take a pic of the field.
